Star trainers give the exact moves they use to whip Jennifer Aniston, Eva Mendes, and Reese Witherspoon into shape

Balance on your sit bones (the bony part of your butt) and extend your arms straight out in front of you, parallel to the floor, keeping your chest and sternum facing upward. Start with your legs off the floor, knees bent so that your calves are parallel to the floor. Extend your legs straight so that your toes are at eye level. Balance here, using your lower abdominal muscles to keep steady. Slowly lower down and hover your shoulders and feet a few inches off of the floor, arms extended along your sides (and also hovering above the floor). Draw your right knee in, extend IT straight up, then bring it down alongside the left leg. Repeat with the left leg. Do this one more time on each side, then sweep back into Boat Pose with the knees bent. Finally extend the legs straight, coming into Full Boat and hold for two breaths.

Of course, pictures of the actual exercises would be nice but lets exercise our brains here as well people! I have heard of these exercises and I highly doubt that is the ONLY thing they swear by. These are very helpful and it's awesome that these trainers share these tips with us just to help us feel as beautiful as these starlets.

Some of these exercised will be very useful! Although I won't find myself trying the pull-throughs at the gym in front of all the guys working out. They're a bit awkward in front of others...though they look great for core toning
